TO ALL WHOM IT MAY CONCERN:

Be it known that I, S. W. c atfrmn-ie 'du Chien, in the county aforesaid; and State oi Wisconsin, have invented a new and useful Improvement in Spinning-Whcel'; .and Ido-herehy, declare that thefollowing is a full, clear,'and exact de'scription --thereof, which will epable others-skilled in theart to make and use the same, reference being had to the accompanying drawings,, forming part of this specificd'tion, inwhich the'd'raming is a side elevation of my improved self-drawing andw-inding spinning-wheel.

'.llhe n: tture of 'this invention consists in a novel and useful modificationof theordinany domestic spinningwheel, enabling the operator to sit while spinning, and thus avoid the labor-of'walkingto and from the head of the wheel,-' to spin the yarn or roving, its, wind it on the cop, as usual. This object is accomplished by attdching the spindle to the end of a radial arm or sweep, which is pulled. backward from theoperat or, to draw the rovingto a position,.where itremains,'to twist the thread o'r yarn, by means of a' weight and pulley acting steadilyj'on the arm during the drawing movement,- but directly under thecontrol of the operator, and for wind ing thcyarn in-to cop-.for'm. ,'The arm bearing the spindle .is nade'to approach the operator, to receive another roll, by means of a treadle, as hereinafter-more particularly described. I

A represents an ordinary inclined frame, supportingthe spinning-"wheel B on the post 0. On the forward end of the frame A are hung two pulleys on the same axis a. The small pnlle'y 6 takes the driving-band b' t'ro'm the spinningfwheel, and the'large pulley e carries the band 0'' that turns the spindle d, placed on the upperehd of the radial arm D, which is also fastened at its foot to the pulley-axis a This axis a is hung in boxes, 0 e5 fixed upon asliding box, 9, that. is adjusted nearer to or further from-thewheel B, as required, to tighten, the pulley-band, by meaps of a set-screw, h, in a stationary block, is. A segmental groove, m,-is formed iii the lower end of the, radial arm D, towhich is fisistened a cord, ml, that lies in the groove, and passes overa small pulley, t', set on a stud, p, on the side of the frame A, just forward of the spinning-wheel. The cord as is con nected at the other end to the treadle g, which is pivoted on the left side at the rear'end of the frame. The upper end of a curved rod, r, with a weight, r, attached to the lower end, is also fastened on the foot of the radial arm D. The weight r is made adjustable on the rod r for the purpose of regulating the dsgreei of tension on the yarn or roving, as hereinafter explained;

The operator, sitting with her too on the treadle, draws the radial arm D toward her, by depress'ingthe' treadle, for the purpose of attaching the roll of wool or cotton or the roving to the spindle, andthen releasing the treadle gently by raising-the toe, and at the same time turning the wheel, as usual, with the right hand. The arm and spindle are drawn-hag]; from the operator by means of the weight 1" on the curved rod 1', which acts on the arm to pull it bacltwi th more or less -force, according to the position of the weight and the leverage it exerts, in order to produce' more or less tension on the yarn while it is drawn out,-while, at the same time-,- the operator may regulate the receding and drawing movement by pressure on the treadle, which is 'counected with. the arm D by the cordm. When the arm D recedes to its limit, it remains in that position, at the will of the operator, long enough to twist the yarn,.andis then bro'ught'forward again, by pressure on the. treadle, to wind the yard on the ,bohbin andreceive another roll of wool or roving. Thus it will he'seen that, by my improved spinning-wheel, the operation of spinning, by a person while sitting, may be peribrmed perfectly, and that the drawing of the yarn by the adinstahle weight is entirely under the control of the operator for roducing asmooth, even.t hread.

' I am aware that spinning-wheels vhave been previously made for spinning while'the operator remains in a sitting position; but the difference between such wheels and-my improvement is of an essential character in two marked particulars: first, instead of drawing the yarn out by the pressure of thei'oot on the treadle, this operation is accomplished, by my arrangement, with a weight, which gives a steady, regular movement to the radial arm, when it recedes, that cannot be imparted by the pressureof' the foot-alone;- second, the ya'rn is elevated between the light and. the operator, so that the hunches and inequalities can be easily detected; and thus the thread made smoother; and, third. the operator sits erect,.loolring upward, with the arms extended and the chest-expanded; insteaiof in a sloping position, looking downwind at the work; as in othor wheels of the'kind, therebypromoting the health of the operator instead of injuring it.

Having thus described my invention, I cla.im as new, and desire'to secure byLetters Potent-'- The curved rod r, with the adjustable weight r, attacheri to the radial arm D, the segmental groove m, cord m, pulley z, and treadle'q, in combination with the sp'mning wheeiC and thespindle d, placed on the upper end'of the arm D, the whole being arranged and operated substantially as and for the purpose herein dese'rib'ed. 1 v
